Rotate the focus knob with your fingers until the object comes into sharp focus. Go a little bit beyond sharp focus until the image just starts to blur again, and then reverse the rotation of the knob, just to make sure you’ve hit the exact focus point. Using the Zoom Eyepiece The TrailHead zoom spotting scope line provides continuous zoom magnification of either 15-45x (on the 65mm) or 20x to 60x (on the 85mm). The magnification is adjusted by rotating the knurled rubber zoom ring on the eyepiece. The arrow indicator and magnification scale show the current magnification setting. Changing the magnification may also require slight refocusing to achieve the sharpest image. For general use, it’s a good idea to start viewing at the lowest magnification until you’ve acquired your viewing target. Then you can zoom-in to a higher magnification to see more detail. Note that as magnification increases, the images will become dimmer; this is an inherent law of physics, and cannot be avoided. Twist-Down Eyecups The spotting scope features a rubber twisting eyecup on the zoom eyepiece. This eyecup is usually left in the up position for use without eyeglasses. To use the spotting scope with eyeglasses, simply grasp the eyeguard and gently twist clockwise to lower it to the desired position. The eyeguard has handy click stops to keep it in place once it is set. Use of the View-Through Carry Case A feature of the TrailHead spotting scopes is that they can be used while still inside the carrying case and mounted on a tripod. This IN 360 Rev A 02/09 Figure 4: The TrailHead zoom spotting scope mounted in the view- through case (angled model shown). is especially helpful in achieving a fast and convenient setup and will keep the exterior of the scope clean. The case can be sealed up quickly to protect the scope from the elements. Although the TrailHead is waterproof it should not be left outside for extended periods of time, even when it is in its carry case. Make certain the TrailHead is oriented properly in the carry case so that the 1/4"-20 hole in the mounting ring can be used to attach the spotting scope to a tripod. Note that you cannot rotate the spotting scope while the TrailHead is in its carry case and mounted on a tripod Care and Maintenance Although the TrailHead zoom spotting scopes are durable and waterproof, it should avoid prolonged, unnecessary exposure to the elements. Keep the spotter in its case and indoors when not in use. If it gets splashed with water, or is used in the rain, the spotting scope will not be harmed. It is internally purged with nitrogen and sealed, so water on the body or optics is not a problem. Simply wipe water off the body with a cloth or towel and use lens tissue to dry the objective and eyepiece lenses after a wet observing session. It is also recommended to leave the spotting scope in a dry place with the caps off overnight to let it completely dry out. Store the instrument in a cool, dry place; storage in a humid environment will result in mold growth on the exterior of the lenses that can destroy the optical coatings. This is not covered by the warranty. Cleaning the Lenses The lens surfaces of the TrailHead zoom spotting scopes are coated with anti-reflection coatings, which can be damaged with careless handling. Avoid touching lens surfaces with your fingers or any coarse material. Clean the lenses if they get noticeably dirty. The dust that builds up on them promotes mold growth, which etches the glass and destroys the coatings. Always use lens cleaning tissue and fluid designed specifically for telescope optical coatings. Providing Exceptional Consumer Optical Products Since 1975 OrionTelescopes.com Do not use regular tissue or fluids made for eyeglasses or household use. Do not disassemble the spotting scope to clean it. To clean the lenses, first blow air on the lens with a blower bulb or compressed air to remove any large particles. Then brush the lens with a soft lens brush and blow air on it again to remove any dislodged particles. Put two drops of lens cleaning fluid on a sheet of lens tissue (never directly on the lens). Wipe the lens gently with a circular motion, taking care to avoid undue pressure or rubbing, which can scratch the coatings. Quickly remove the excess fluid by wiping with a clean, dry lens tissue. For the large objective lens, clean only a small area at a time, using a fresh lens tissue on each area. Specifications #9520 15-45x65mm Straight Objective lens diameter: 65...
